PATENT OFFICE.

RICHARD C. I-IOLTON, OF CLOVIS, NEW MEXICO.

PET-COCK WRENCH.

Application filed September 14, 1923.

To all whom t may concern.'

Be it known that I, RICHARD C. HoL'rorIJ a citizen of the United States, residing 'at Clovis, in the county of Curry and State of New Mexico, have invented a new and useful Pet-Cock lVrench, of which the following is a specification.

This inventionrelates to oil testing devices to be used in connection with crank cases equipped with petcocks which require to be opened to determine whether or not oil is needed.

The object of the invention is to provide a device of this character especially designed for use at filling stations and in garages to prevent the oil on the opening of the petcocks from being discharged onto the floor. Y

Another object is to so construct such a device that the oil from the petcocks will be caught in a suitable vessel which may be emptied without touching the vessel with the hands.

`With the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.'

In the accompanying drawings:-

Figure 1 represents a side elevation partly in section of the tester constructed in accordance with this invention.

Fig. 2 is a top plan view thereof; and

Fig. 3 is a side elevation of the oil vessel with parts broken out and in section, the dotted line position representing the vessel when tilted for emptying it.

As is well known the crank cases of Ford cars are equipped with spaced petcocks arranged in different vertical planes which are designed to be used for determining whether or not oil is needed in the crank case. When these petcocks are opened oil iows out and unless there is something to catch it, it is discharged onto the fioor which is objectionable for obvious reasons. The device constituting this invention is designed to overcome this objection and comprises an oil receiving vessel 5 suspended from one end of the usual testing key 1 which is composed of a metal rod having a Serial No. 662,711.

Ihandle 2 at one end and a cock engaging jaw 3 at the other with a pin or linger leXtending laterally from said jaw the object of which is to open the bore in the petcock should it become obstructed. This key is of the usual well known construction and has mounted thereon the oil receiving vessel 5 which is comparatively small in size holding approximately about a half a pint and is suspended from the rod adjacent the jaw 3 by means of a cross bar 7 having a substantially U-shaped outwardly extending offset 8 through the legs 9 of which the rod 1 loosely passes as shown clearly in Fig. 1. This handle or bar is held against longitudinal movement on the rod by means of a collar 10 carried by the rod.

The vessel 5 has a pouring lip 6 to facilitate emptying thereof.

In the use of this device the vessel is supported on the rod with its mouth 6 positioned at one side thereof and with the.

cock engaging jaw 3 located at a point direc'tly over the center of the vessel so that when the key is engaged with the petcock and turned to open it the oil flowing out of the cock will be caught by the vessel thus effecting a great saving in the time and labor in scrubbing and cleaning floors in O'arages andthe like. After the vessel has been filled or nearly so, the waste oil may be emptied therefrom by simply turning the rod to cause the pin or finger to engage the front edge of the cross bar 7 as shown in Fig. 3 thereby causing the vessel and rod to move in unison and permit the oil to be poured out of the vessel without touching it with the hands.

Various changes in the form, shape, proportion and other minor details of construction may be made without departing from the principle or sacrificing any of the advantages of the claimed invention.

I claim 1. A device of the class described comprising a petcock key having an oil receiving vessel swingably mounted thereon cooperating means on said key and vessel whereby the vessel may be tilted to empty its contents without touching it with the hands.

2. A device of the class described comprising a petcock key having an oil receiving vessel swingably mounted thereon adjacent its outer end, said vessel having a pouring lip at one side and cooperating meensen said key and Vessel to Cause the Y Vessell toV turn in unison with the key to dapt the contents thereof to be emptied without touching the Vessel with the hands. Y

device of the dass described comprising a. peteoek key having a, ]aw'et`0ne y end for engaging the peteoek, enoil reeeiv'- ing VVessel mounted on seid key in it plane below seid jaw', seid vessel having :L cross `l0 Vlearnt its upper end With un offset therein through which said keyv loosely passes whereby the vessel is suspended from the key.

In testimony that I claim the foregoing als my own, I vhave hereto affixed my signature in the presence of two Witnesses.
